Abstract: A waste system is disclosed. In some embodiments, the waste system includes a vacuum cell, a flexible waste container, and a vacuum source. The flexible waste container may have at least one flexible membrane at an interface between the flexible waste container and the vacuum cell. The vacuum source may be configured to suction air out of the vacuum cell to generate a negative pressure in the vacuum cell. The vacuum source discharge is generally odorless as it is separated from the waste. This odorless discharge can enter occupied aircraft compartments. The negative pressure in the vacuum cell acts on the flexible waste container to generate a (second) negative pressure in the flexible waste container. The negative pressure in the flexible waste container acts on an interface between a toilet and the flexible waste container to pull waste from the toilet into the flexible waste container.

Abstract: A system for waste system pressure management is disclosed. In one or more embodiments, the system includes an electronically controlled valve and a controller communicatively coupled to the electronically controlled valve. The electronically controlled valve is coupled to a suction path of an aircraft waste system. The controller is configured to determine a pressure differential between an aircraft cabin and a vacuum source for the suction path. The controller is further configured to generate one or more signals to actuate the electronically controlled valve from a first position to a second position to regulate a pressure in the suction path when the pressure differential between the aircraft cabin and the vacuum source exceeds a threshold pressure differential. In embodiments, the electronically controlled valve is configured to allow more airflow through the electronically controlled valve in the second position than in the first position.

Abstract: In a preferred embodiment, a retrofittable PRM lavatory complex occupies the same footprint as a preexisting outboard dual-lavatory complex. The two lavatories are separated by a common articulating wall that is typically positioned in a standard operating position in which the lavatory complex operates as a standard dual-lavatory complex. The common wall may be moved by a flight attendant or passenger to a PRM position in which the lavatory spaces are combined to accommodate a person with reduced mobility. In the most preferred embodiments, the common wall may be articulated to the PRM position from within the lavatory with the doors closed, which facilitates the conversion to a PRM lavatory and advantageously avoids intrusion into the aisle space during the conversion.

Abstract: A wall mounted stowage compartment for a passenger cabin of an aircraft includes a housing having a rearwardly facing wall mounted to a forwardly facing interior monument wall. The stowage compartment is located under an aft most passenger seat adjacent to the forwardly facing interior monument wall. The stowage compartment includes a stowage compartment drawer, and a protective breathing equipment compartment is mounted to a side wall of the aircraft cabin monument, and includes a forwardly facing edge that follows a contour of the forwardly facing wall of the aircraft cabin monument extending from a forwardly facing recess to the floor of the cabin.

Abstract: A combination lavatory and galley arrangement for aircraft includes a lavatory portion having adjacent inboard and outboard lavatories, and a galley portion, and can be located aft of aft aircraft aft doors, and can at least partially rearwardly extend into the aircraft's aft pressure dome. The inboard and outboard lavatories can be separated by a movable wall or partition to provide access for persons with restricted mobility, and can be provided in a modular housing to facilitate retrofit assembly within an aircraft. The movable wall can be an articulating movable lavatory partition movable between a first, linearly extended configuration and a second, folded configuration in a stowed position to provide entry for persons with restricted mobility.

Abstract: An interior ceiling panel system includes a ceiling panel mounted in a ceiling area, a first airflow directing panel in a first side of the ceiling area defining an airflow passage, and a second airflow directing panel in a second side of the ceiling area, defining an eddy space. An airflow supply source introduces airflow into the ceiling area, and the second airflow directing panel provides an obstruction that creates an eddy in the eddy space that incoming airflow with air in the cabin. One or more speakers project sound energy upward toward the ceiling panel, which deflects sound energy to provide more uniform sound levels in the cabin.

Abstract: An electrically activated latch for aircraft stowage bins includes an overhead stowage bin module having a stationary support structure and a movable stowage bin portion. An electrically operated stowage bin latch mechanism latches the movable stowage bin portion in a closed position and unlatches the movable stowage bin portion to an open position. An electrically operated stowage bin activation switch operates the stowage bin latch mechanism, allowing the aircraft stowage bins to be locked by independently controlling the overhead stowage bins through the aircraft cabin management system, or by control of the latch by the stowage bin activation switch.
